METAL=CRIMPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 369,876, dat September 13, 1387- Application filed January 12, 1887. Serial No. 224,164. (No model.)

To all whom it may concern:

1 3e it known that I, FRANK R. PAOKHAM, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Metal-Crimping Machines, of which the following is a specification.

My invention relates to metal-crimping machines, and particularly relates to that class of machines adapted to crimp the ends of stovepipes, bucketlids, &c., to produce a taper thereon.

It also relates in its nature to improvements on the machine described and set forth in my i'igzstgers Patent No. 349,355, of September 21,

My invention consists, first, in a novel arrangement for supporting the upper roll, whereby the said roll may be moved bodily to vary the depth of the serrations or crimpspro duced thereby, means being provided for varying the angle of said roll to secure a variation in the taper produced thereby.

My invention further consists in a novel arrangement for securing the rolls on the respective shafts or either of them, so that the ends of said rolls will stand flush with the ends of the said shafts in crimping bucket-lids and similar articles.

My invention further consists in various constructions and arrangement of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, which form part of this specification, Figure l is a side elevation of a device embodying my invention,

the side cover or bearing-plate being removed therefrom. Fig. 2 is a sectional elevation of the same on the line m 00. Fig. 3 is a side elevation showing the respective parts in a different position of adjustment, some of the parts being modified slightly in .construction, as hereinafter more fully'set forth. Fig. 4 is a sectional view of the same on theline y 3 Fig. 5 is an inside view of the upper-roll-supporting device and the side cover in an inverted position. Fig. '6 is a sectional view of the same on the line 2 2. Figs. 7 and8 are detail views of the end of the main shaft and roll, showing the method of removing or securing said roll in place. i

In the accompanying drawings, A represents the main frame, which is provided near thebottom thereof with a bearing, a, for the main shaft 13 and with an upwardly-extending side Wing, a. Supported 011 the side wing, at, in the manner hereinafter more fully described, is the upper rollsupporting device 0, provided with a suitable shaft or journal, b, for the crimping-roll O and the ogee or beading roll O The corresponding lower rolls, B and B, are supported on the main shaft B, and are revolved thereby, in a manner hereinafter more fully described. The crimping-rolls B and O are preferably made of uniform size and provided with a series of serrations of a uniform depth throughout, the graduallydecreasing depth of serrations formed by the machine in operation, thus producing the taper, being secured by placing the respective shafts at an angle, the length of the taper being varied by the variations in the angle of the shaft.

Means are provided for moving the upper roll to and from the lower roll to introduce and remove the work therefrom and to graduate the depth of the flutes or serrations to be formed. In the machine set forth in my above-mentioned patent this was accomplished by having the upper-roll-supporting device pivoted at the rear end, means being provided for changing the position of the pivot in order to change the angular position of the crimping-rolls. In my present machine I dispense with the use of the pivotand provide a movable side or bearing plate on which the upperroll-supporting device is adapted to move, means being provided by which the position of the side or bearing plate may be changed to change the angular position of the roll supported thereby. This I preferably accomplish as follows: The upper-rollsupporting device 0 is provided at the rear end with a frame, bf, which is provided on each side with projecting lugs or bearings b, adapted to rest, respectively, against the side wing, a, and the side or bearing plate, D. This side or bearing plate, D, is provided with projecting ribs 0 c,adapted to fit snugly in the frame 1). The side or bearing plate, D, is secured to the side wing, a, by means which will permit it to be turned to different positions thereon, thus turning the upper-roll-supporting journal and varying the angle thereof in relation to the main shaft B. This may be accomplished by providing on the side or bearing plate, D, a small projection, 0', adapted to extend into an opening, a in the side wing, a, and a screw threaded stud, 0, adapted to extend through a slotted opening, a in the said side wing. A thumb-nut, 0 is provided on the end of the said stud, by means of which the bearingplate D may be firmly secured in any desired position of adjustment on the side wing, at. The bearing-ribs c are made slightly longer than the depth of the frame I), so that when the bearing-plate Dis drawn tightly against the side wing, at, the frame b will move freely thereon. (See Fig. 6.)

Located in the frame I), and resting at one end against the side of said frame and at the other against a projecting lug, a, on the side wing, at, is a spring, 6*, adapted to press the supporting-frame and its roll upwardly, thus holding the roll 0 out of engagement with the roll B. Immediately above the spring 6 and adapted to bear on the top of the supporting-frame b is an adjusting-screw, d, by means of which the engagement of the rolls 0 and B may be graduated as desired. It will be seen that by this construction the upper roll may be moved to or from the lower roll, as desired, the movement being accomplished uniformly at each end of the roll. By changing the position of the bearing-plate the angular position of the rolls may be readily changed as desired, after which any depth of flute or serration may be formed in the article operated upon without varying the angularity or taper thereof.

The lower main shaft, B, I make of a uniform size throughout, so that it may be moved longitudinally in the main bearing a. This shaft B projects at the rear and is provided with a handle, E, preferably secured thereon by a set-screw, e.

In order that the rolls may be readily .removed when desired, and to provide for securing the crimping-roll flush with the end of the shaft when the ogee or beading roll is re moved for the purpose of crimping bucketlids or similar articles, I provide in the shaft B small holes or pocketsf, adapted to receive small removable pins f. In the ends of the respective rolls I provide small depressions or socketsf into which the pins are adapted to enter.

The handleE is adapted to bear against the rear end of the main bearing a. The roll B is adapted to bear against the front end of the bearing a. When the handle is secured on the shaft B, the said shaft is held against longitudinal movement through its bearing. By loosening the set-screw, however, the shaft may be moved longitudinally sufficiently to Withdraw thepinsf from the socketsf", after which the pins f may be removed from the shaft B, allowing the rolls to be changed as desired. By removing the ogee or beading roll and replacing the pinsf in the outer hole inthe shaft B, the said shaft may be slipped through its bearing until the pinf engagesin the socket of the crimping-roll B., The bandle E is moved forward on the shaft until it comes against the bearing a, after which it is again secured in place, thus leaving the outer end of the crimping-roll flush with the shaft and unencumbered for crimping short flanges or similar articles. I preferably provide in the rear end of the shaft B a small groove or keyway, e, in which the end of the set-screw is adapted to enter, so that the handle E may b may be readily adjusted longitudinally and I held in any desired position of adjustment. In Fig. 3 I have also shown the construction of the bearing-plate D slightly modified, the projection 0 being dispensed with, the plates being adapted to be adjusted by the stud 0', Which extends through a circular opening in the side wing, a, and forms a pivot for said plate. The plate D is held in different positionsofadjustmentbytighteningthethumb-nut c. In this case it may be desirable to provide the face of the side wing, a, and one of the bearing-ribs c with a series of serrations, 9, (see Figs. 3 and 4,) by means of which the plate D will be held securely from turning when the thumb-nut c is tightened. In this construction the spring 12 which serves to move the frame I), is supported directly on the stud 0", as shown in Fig. 4.

It is obvious that various other modifications may be employed without departing from the spirit of my invention.

I preferably provide each of the crimpingrollswith a small groove, h, which extends around its periphery,cutting the flutes or serrations therein, and I arrange the gage F so that the work inserted between the rolls never comes beyond the said groove. By this construction that portion of the roll which is inside of the groove h is protected from wear and serves the purpose of transmitting motion to the upper roll in case theroll becomes much worn by use.

Having thus described my invention, I
